A user reported a bug in NVDA which I've tracked down to a bug in
lou_translate when translating a string with spaces at the end including
typeforms. In this case, the spaces at the end are stripped. This occurs
even if the table being used doesn't handle typeforms. In Python:
>>> louis.translate(["louis/tables/en-us-comp8.ctb"], u"ab ",
typeform=(0, 0, 0, 0), mode=louis.dotsIO, cursorPos=0)
